Latest Patents

Kushal holds a patent for "Row level security in natural language question answering." This patent describes a natural language question (NLQ) query service within a service provider network that provides row level security (RLS) for autocomplete during the entry of NLQs and fuzzy matching in NLQ answering. The rules take the form of per-user predicates, such as "Tim can only see rows with region=US." In configurations, a complex extraction and preprocessing pipeline is utilized to extract distinct combinations of values against RLS predicate 'rule keys.' These distinct values are indexed along with grouped rule keys to enable pushing down predicates at autocomplete time. This innovation allows for part of the RLS rule handling to occur during the ingestion time of a dataset, rather than at query time, thus meeting latency goals. Additionally, a single logical document of unique cell values can be split into multiple documents with a subset of rule keys to handle scalability limits.
